摘　　要：Catalytic characteristics of magnesium chloride supported rare earth catalyst system of Nd(OR) 3-n Cl n(n=0,1,2) in polymerization of butadiene was investigated.The result indicated that the ionic electronegativity of magnesium and content of chlorine as measured in mumber of atom are important factors that affect the catalytic characteristics.Catalytic characteristics of magnesium chloride supported rare earth catalyst system of Nd(OR) 3-n Cl n(n=0,1,2) in polymerization of butadiene was investigated.The result indicated that the ionic electronegativity of magnesium and content of chlorine as measured in mumber of atom are important factors that affect the catalytic characteristics.
